Flatness detection device for building wood processing

Abstract

The invention relates to a flatness detection device for building wood processing and relates to the technical field of building wood. The device comprises a fixed seat; the inner wall of the top of the fixed seat is fixedly connected with a first electromagnet; the inner top wall of the fixed seat is fixedly connected with a first magnetic rod; the bottom of the first magnetic rod is fixedly connected with a movable block; the inner wall of the top of the movable block is fixedly connected with a magnetism isolating plate; the inner wall of the left side of the movable block is fixedly connected with two symmetrical positive pole plates; and the inner wall of the right side of the movable block is fixedly connected with two symmetrical negative pole plates. According to the flatness detection device for building wood processing, through cooperative use of a dielectric plate and a resistor, when wood is uneven, a telescopic block moves up and down under the action of a spring, and the dielectric plate changes the relative area of the positive pole plates and the negative pole plates, so that the circuit voltage passing through the negative pole plates is changed; and therefore, the on-off of the resistor is realized, the real-time control effect is achieved, the practicability is improved, and meanwhile, the production efficiency is also improved.

Description

technical field [0001] The invention relates to the technical field of building wood, in particular to a flatness detection device for building wood processing.

[0002] Wooden boards are wooden boards made of complete wood. These boards are durable and have natural textures. They are the best choice for decoration. This type of board is expensive. Wooden boards are generally classified according to the real name of the board. There is no uniform standard specification. Wooden boards are Materials that are often used in home decoration, when purchasing wood boards, be sure to see its grain and clear grain. Generally, it is best not to have broken grains. In the current production process of wood, the flatness is mostly detected by human eyes. prone to error

[0003] Since there is no machine testing equipment in the current production equipment, most of the time it is necessary to manually judge the flatness of the plank, but manual judgment often causes errors, resulting in uneven quality of the plank produced, which greatly reduces production efficiency. Delay the production schedule, and may also cause waste of wood
